%description
Provide model averaging-based approaches that can be used to predict
personalized survival probabilities. The key underlying idea is to
approximate the conditional survival function using a weighted average of
multiple candidate models. Two scenarios of candidate models are allowed:
(Scenario 1) partial linear Cox model and (Scenario 2) time-varying
coefficient Cox model. A reference of the underlying methods is Li and
Wang (2023) <doi:10.1016/j.csda.2023.107759>.
